Folk,
This was given to me as an example of a
script to fix the order of loading of devices.
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
remove snd-emu10k1 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-emu10k1
alias snd-card-1 snd-intel8x0
remove snd-ca0106 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-ca0106
options snd-intel8x0 index=1
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias snd-card-2 snd-usb-audio
options snd-usb-audio index=2
I understand an alias of course. These are my questions.
"options" isn't a shell command. What is it?
"remove" also isn't a shell command. What is it?
What is the objective of "alsactl store 0 >/dev/null"?
The modprobe command unloads driver module
and "causes modprobe to ignore install and remove
commands in the configuration file ...". Without
drivers, how do sound devices work?
Why is a "remove" and a "modprobe" command squeezed onto
one line rather than on successive lines?
Why is the order of these commands different for each device?
Such a script belongs in modules.conf?
Thanks for any answers, ... Peter E.
